Think about it. Our planet has a certain carrying capacity, or what the Club of Rome — a think-tank of academics, business leaders and politicians — called the "limits to growth" in their famous 1973 report. They warned that Earth was beginning to reach its carrying capacity, and soon ...
Describing the water cycle would involve stating observations about rain, clouds, and water flow on the Earth's surface. 14 Explaining often requires a deeper understanding of a subject because it involves linking facts to theories, principles, or laws to clarify how something works or why ...
How is the sunspot cycle directly relevant to us here on Earth? If the ice at the poles melts and flows towards the equator, how will it affect the duration of day-night? Define the term sublimation. Explain why a body of water freezes from the top down rather than f...
Explain why the temperature at the equator is always hot and the temperature at the poles is always cold, despite the passage of seasons. What can change the duration of day-night (i.e, time) on Earth? Is magnetic declination changing with switch...
and headphones is, of course, size. A loudspeaker needs to set all the air moving in a room so you can hear the sound it's making, but the speaker in a headphone only has to move the volume of air inside your ear canal. That's why it can be so much smaller and more discreet....
Earth's carbon cycle maintains a stable climate and biosphere on geological timescales. Feedbacks regulate the size of the surface carbon reservoir, and on million锕渆ar timescales the carbon cycle must be in steady state. A major question about the early Earth is whether carbon was cycled ...
Earthquake nests are volumes of the Earth characterised by high, persistent and spatially isolated seismic activity58. The Bucaramanga nest, Colombia, is the most dense seismic nest on Earth59. There, an average of 8 events per year (with body wave magnitudes larger than mb 4.7)60within a com...
How? Just like in a refrigerator, the coolant flows through a compressor unit and some condensing pipes, which turn it back into a cool liquid ready to cycle round the loop again. What happens to the heat? In the unit outside the building, there are lots of metal plates that dissipate ...

Earth and have been tentatively observed in the Venusian atmosphere at abundances many orders of magnitude greater than those predicted given their short photochemical lifetimes10,11,12,13. A plausible life cycle for a strictly aerial biosphere in the clouds has been investigated11, and a suite of...
